SAN FRANCISCO — A federal jury has found three Pittsburg police officers used excessive force when they deployed their Tasers simultaneously against an Oakley man in 2008.

Jurors in U.S. District Court in San Francisco on Friday sided with Frederick Jackson, 43, in his case against Officers Cory Smith, Sankara Dumpa and Gerald Lombardi in connection with incident in which the three officers all shocked Jackson at the same time with their Tasers, and one shocked him a second time seconds later.

The jury awarded Jackson $250,000 in damages, plus attorneys fees and punitive damages. An appeal in the case is certain, according to the officers’ attorney, Peter Edrington, who called the verdict a “miscarriage of justice.”

Police were summoned to Jackson’s former home in Pittsburg on March 30, 2008 after several people, including Jackson, became involved in a physical altercation outside and 911 callers reported a shirtless man holding a knife or gun.

Jackson was shirtless and intoxicated, but not armed, when Officer William Hatcher began to search him. Jackson had seven prior felony convictions.

Edrington said the 300-pound and very muscular Jackson broke free from Hatcher and used his elbow to knock the 180-pound officer backward. At that point, the three backup officers deployed their Tasers. Jackson’s attorneys argued that Jackson was provoked by one of the officers threatening to use the Taser on Jackson’s 15-year-old daughter. Edrington said that was a lie intended to damage the officers, all of whom have “exemplary records.”

“If an officer perceives that another officer is in threat of harm, he may deploy his Taser,” Edrington said. “In this case, all three officers independently perceived danger to Officer Hatcher, and deployed their Tasers, and that is precisely what that law allows them to do.”

The voltage from the three, 1200-volt Tasers resulted in 1200 volts into Jackson’s body. The voltage does not increase based on how many Tasers are deployed, Edrington said.

Jackson fell onto his face during the incident and was hospitalized for five days with a broken orbital bone.

Eugene Zinovyev, one of Jackson’s two attorneys, said the trial revealed that the police department is not closely monitoring recorded Taser use by its officers.

“It was a jury of very regular people sending a message to the Pittsburg Police Department: You can’t go on business as usual. You have to be concerned about the use of Tasers,” Zinovyev said.
